Charcoal Mellowing Vat

[SmokyMtn]

I haven't seen or heard anyone make a vat in hobby scale. Searching only showed the discussion of if actually done anything. And I don't want to argue if it has any benefit.

Since day one I have caught my spirits in a funnel filled with charcoal. And now I want to make or buy something that is a larger vat to add charcoal surface area.

Thoughts are make a copper sheet downspout 3 or 4 inch wide x 6 foot long. Fill with charcoal, pour over, and drain into jars. Cost would be high but would drain through a lot of charcoal.

Second idea is to buy a SS stock pot and make a drain. Cost would be lower but the drain has me puzzled since I don't own a welder. Time in charcoal would be less but I could collect and pour back over the coals multiple times.
